1 Claim. (Cl. 155-130) The present invention relates to looks for davenports and particularly for the sectional type of davenport.

The primary object of the invention is to provide a detachable locking mechanism for holding one section of a davenport connected to another section.

A further object of the invention is to provide a locking mechanism that can be easily installed on the davenport.

A still further object of the invention is to provide a lock mechanism of the class described above having a safety feature which will prevent accidents happening by the sections of the davenport separating while being used.

Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings in which:

Figure 1 is a perspective view of a sectional davenport assembly incorporating the invention;

Figure 2 is a fragmentary transverse vertical sectional view taken along the line 22 of Figure 1, looking in the direction of the arrows;

Figure 3 is a fragmentary longitudinal sectional view taken along the line 3-3 of Figure 2, looking in the direction of the arrows;

Figure 4 is an inverted fragmentary plan view of the locking mechanism shown attached to the sections of the davenport and in unlocked position; and

Figure 5 is a view similar to Figure 4 with the locking mechanism shown in locked position.

Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference character D indicates generally a sectional davenport which includes three sec-- tions 10, 11 and 12, separated along the lines 13 and 14.

The invention consists of a locking assembly L which includes an angle bar 15 attached to the bottom 16 of the davenport section 11 by screws 17 which enter the framework (not shown) of the davenport. Pivotally mounted on both ends of the angle bar 15 by bolts 18 are latches 19.

The latches 19 are operated by connecting links 20 connected thereto by pivot pins 21. The opposite end of the links 20 are pivotally connected by pivot pins in spaced apart relation to walking beam 23. The walking beam 23 is pivotally connected to a bracket 24 by pivot pin 25. The bracket 24 is mounted on the angle bar 15.

A hand lever 26 is pivotally connected by a bolt 27 to a frame member 28 extending from the front end of the angle bar 15. A connecting link 29 has one end thereof pivoted to the lever 26 by pivot pin 30, and its opposite end pivotally connected to the Walking beam 23 by pivot pin 31. Located near the end of the frame member 28 is a stop pin 32 to hold the hand lever 26 in the position shown in Figure 5.

The latches 19 have hooks 33 fonned on their outer ends and the hooks 33 engage the ends 34 of the angle bar 35. The angle bar 35 is secured to the underside Patented Sept. 15, 1959 See of the adjacent section 10 of the davenport D, by screws 36.

The connecting link 29 consists of a pair of flat bars 40, 41 having their adjacent end portions overlapping and engaging. The bar 40 has a pair of longitudinally extending end to end related spaced apart slots 42 formed therein, a headed guide bolt 43 is fixed to the free end portion of the bar 41 and extends through the inner slot 42 of the bar 40. A wing bolt 44 is releasably secured to the central portion of the bar 41 extending through the outer slot 42 in the bar 40, bearing against the bar 40 to lock the bars 40, 41 together for movement as a unit.

In the operation of this new and improved locking device for sections of sectional davenports D, the sections 10-11 are brought towards one another into contacting relation to each other, the hand lever 26 is in the position shown in Figure 4 and by moving this lever to the position shown in Figure 5, the hooks 33 of the latches 19 engage the ends 34 of the angle bar 35, holding the two sections 1011 of the davenport D tightly together, as illustrated in Figures 1, 3 and 5.

When the lever 26 is brought almost to the position illustrated in Figure 5, it is sprung down slightly below the pin 32, moved to innermost position and released behind the pin 32, where it is held in locked position.

When the sections of the davenport D are used separately the wing bolt 44 is loosened and the bar 41 is moved on the bar 40 to permit the handle 26 to be swung beneath the section 10 while leaving the latches 19 beneath the section 10 also. The wing bolt 44 is then tightened to secure bar 40 to the bar 41 in the adjusted position. When it is again desired to use the davenport D in connected relation, the bars 40, 41 must be adjusted and locked together as illustrated in Figure 4.

Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claim.

What is claimed is:

A latch mechanism for releasably securing together adjacent sections of sectional davenports comprising an elongated angle iron frame member secured in depending relation beneath one of said sections parallel to and adjacent one side edge thereof, an elongated angle iron keeper bar secured in depending relation beneath an adjacent section parallel to and adjacent the side edge thereof in contact with said one side edge of said first named section, a latch hook pivotally connected to each end of said frame member, a hand lever pivotally mounted beneath and secured to said first named section, a walking beam pivoted on said frame member, link means connecting said hand lever to said walking beam, a link connecting each of said latch hooks to said walking beam, a stop pin secured to and depending from said first named section for engaging and holding said hand lever in position with said hooks in latching engagement with said keeper, said link means connecting said hand lever to said walking beam being longitudinally adjustable to permit said hand lever to be engaged by said stop pin with said latch hooks in retracted position, and comprising two bars having their adjacent end portions connected by pin and slot means.
